JOHN IV. FAESSLER, OF MOBERLY, MISSOURI.

STEEL-HARDENING MACHINE.

SPECIFICATION forming part of Letters Patent No. 779,841, dated January10, 1905;

Application filed August 8,1904. Serial No. 219.932.

To all whom it may concern:

Be it known that 1, JOHN W. FAESSLER, a citizen of the United States,and a resident of Moberly, Missouri, have invented certain new anduseful Improvements in Steel-Hardening Machines, of which the followingis a specification containing a full, clear, and exact description,reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in steel-hardening machines; and itconsists of the novel features herein shown, described, and claimed.

In the drawings, Figure 1 is avertical central section on the line 1 1of Fig. 2 and looking in the direction indicated by the arrow andshowing the operation. Fig. 2 is a top plan view as seen looking in thedirection indicated by the arrow in Fig. 1, the steel being removed.

Referring to the drawings in detail, my improved steel-hardening machineis preferably cast in two pieces and comprises the cupshapedhardening-receptacle 5; the waterjacket 6 around the receptacle 5 andforming the -water-chamber 7, said water-jacket extending a shortdistance above the upper end of the receptacle; the water jacket cap 8,screw-seated upon the upper end of the wator-jacket 6; the receptacleextension 9, extending downwardly from the inner edge of the cap .8 inalinement with the wall of the receptacle, there being a thindischargeopening 10 extending entirely around the receptacle between theupper edge of the receptac'le and the lower edge of the flange, thewidth of said opening being adjustable by adjusting the cap u p and downupon the jacket;

a jam-nut 11 upon the jacket 6 and holdingthe' cap 8 in its adjustedposition, the inletnipple '12p'roviding a water-passage to thejacket-chamber 7 and the outlet-nipple 13 leading from near the upperend of the receptacle 51 outwardly through the chamber 7 and through thejacket 6.

' T-he supply-pipe 14 may be connected to the in'let-nipple12 by theunion l5,'or by any suitable means, and. the outlet or overflow pipe 16maybe connected to the nipple '13 by a union 17 or by any other suitablemeans.

In the operation of my improved steel-hardening machine fresh waterpasses through the supply-pipe 14 into the chamber 7, and from thechamber 7 the water is discharged in a thin sheet through the opening10, said water meeting at the center of the receptacle 5 and fallinginto the receptacle, and the water will flow out of the receptacle5through the nipple 13. The cold water will fall to the bottom of thereceptacle,and the warm water will overflow and run out of thereceptacle. As before suggested, the flow of water may be adjusted andregulated by adjusting the cap 8 to increase or decrease the width ofthe slit 10. The piece of steel to be hardened, such as that indicatedby the tool 18, is inserted downwardly into the receptacle 5 through thesheet of water, thus bringing fresh water into contact with the surfaceof the steel as it passes downwardly, thereby greatly improving andfacilitating the process of hardening and temporing. I claim 1. In asteel-hardening machine, a suitable receptacle; a jacket around thereceptacle; 8.

cap upon the jacket; a flange extending from the cap in alinement withthe receptacle, and forming a discharge-opening extending entirelyaround the receptacle; and an-overflowpipe leading from the receptacle;

2. In a steel-hardening machine, a suitable receptacle; a jacket aroundthe receptacle; a cap adjustably mounted upon the jacket; 8. flangeextending downwardly from the inner e eee th asefire-m e a thindischarge opening around the upper edge of the receptacle; means forleading water to the jacket; and means for leading the overflow from theupper end of the receptacle.

3. In a steel-hardening machine, a suitable receptacle open at the top;a jacket around the receptacle; a cap upon the jacket; a flangeextending downwardly from theinner edge of the cap and closing thejacket and forming a thin opening from the jacket into the receptacle,there being an opening through the cap inside of the flange in alinementwith the open upper end of the receptacle; means for leading water tothe jacket so that it will discharge in a thin sheet into thereceptacle; and

means for leading the overflow from the upper end of the receptacle sothat the liquid in the receptacle will maintain a water-level below thedischarge-opening.

4. In a steel-hardening machine; asuitable receptacle open at the too; ajacket around the receptacle; means for leading Water to the jacket;means for discharging water from the jacket in a thin continuous sheetfrom all sides 10 into the receptacle; and means for leading theoverflow from the receptacle, so that the liquid in the receptacle willmaintain a water-level below the discharge; substantially as specified.

In testimony whereof I have signed my name to this specification inpresence of two suh- 5 scribing witnesses.

JOHN W. FAESSLER.
